A 14-year-old Detroit girl says that a neighbor shot and killed JoJo, her 1-year-old Chihuahua, because he wasn’t on a leash and was making too much noise. The licensed gun owner, however, told police that he gunned down the tiny dog because it was threatening him. The girl, who WJBK declined to identify, said that she had gone inside for a few minutes while JoJo ran free in the yard.
